SPECIFICATION forming part of Letters Patent N 0. 547,006, dated October1, 1895.

Serial No. 544,337- (No model.)

T0 at whom it 77mg concern.-

Be it known that I, JOHN A. FREY, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Lamps, Lamp-Stoves, &c., of whichthe following is a specification.

My invention relates to lamps; and it consists in a novel constructionof the wick-raising devices, as hereinafter set forth and claimed.

In the drawings, Figure 1 is a vertical sectional view of a lamp havingmy improve ments applied thereto; Fig. 2, a sectional view on the line00 0c of Fig. 1; Fig. 3, a sectional perspective view of thewick-raiser; Fig. 4, a top plan view, partly in section; and Figs. 5 and6, views illustrating modifications.

A indicates the body of the lamp, and B the central draft-tube, whichreceives and is surrounded by the wick O. In the top of the bodyA is acentral opening (1, around the edge of which is the raised flange b, asshown in Fig. and fitting into this opening and held thereinfrictionally or by catches is the short tube-section D, which, when inposition, eX- tends up to the top of the draft-tube, the said section Dbeing provided with a lateral flange or rim 0, which rests upon theupper face of flange b and holds the section D in proper relation to thedraft-tube. The perforated flared jacket F fits over the tube-section D,and in the preferred construction is made separate and readilydetachable from the tube-section. From the foregoing it will be seenthat when it is desired to place a new wick in the lamp it is onlynecessary to remove the short tubesection D, thereby exposing the upperend of the draft-tube and greatly facilitating the placing of the wickupon the tube. So, too, by removing this section D it may be readilycleaned and the lamp prevented from becoming fouled, a result which isfurther insured by making the perforated member F detachable from thetube-section D.

In order to raise and lower the wick and to provide for readily taking anew hold upon the latter as it burns away, I provide two arms, pivotedtogether and provided with handles, whereby they maybe raised andlowered bodily, and also moved toward and. from each other, the saidarms working in suitable vertical guides. This will be readilyunderstood upon reference to Figs. 1, 3, and 4, in which G G representthe arms as a whole, each of which comprises a curved toothed portion d,an outwardly-extending bar e, and an upright part or portionf,terminating in a lateral handle or thumb-piece g. The upright partfofeach arm G has at its inner edge a lateral flange h and at its outeredge one orv more eyes c', through which latter the hinge rod or pinjpasses. The flanges h are embraced by a grooved or channeled upright H,secured fixedly within the lamp body, the grooves orchannels being ofsuch width as to allow a little play to the upright partsf when thelatter are rocked upon the pivot-pin, as shown in Fig. 4. While there isthis slight play the wick-raiser as a whole will be properly guided inits vertical movements. A spring I is arranged at any suitable point onthe arms and tends to hold them together, or in such position as tograsp the wick.

When it is desired to raise the wick, the handles or thumb-pieces g arelifted, the wickraiser being guided by the upright H, and when it isdesired to lower the wick it is only necessary to press down upon thethumbpieces. When, however, it is desired to adjust the wick-raiserrelatively to the wick, it is only necessary to press the thumb-piecestogether and separate the toothed arms d, as shown in Fig. 47, whereuponthe wick-raiser may be raised or lowered relatively to the wick, asdesired, and when the desired adjustment has been effected thethumb-pieces are released and the spring draws the arms at d toward eachother to grasp the wick.

The arms G G are shown as made each of a single piece of metal, but theymay obviously be modified considerably in form without departing from myinvention.

Where the invention is applied to oil stoves or heaters, the tube B andthe tube-section D will be made oblong in cross-section, and hence inusing the term lamp I do not wish to be understood as restricting myselfto the use of the cylindrical tubes, nor to alamp in its restrictedsense.

Where the invention is applied to large be made of several pieces. Thedevice may heating lamps or stoves, it will be found inconvenient, onaccount of the heat, to raise the wick by lifting the thumb-pieces g,and I therefore provide a handle or lever 74;, which is pivoted to thebowl or body A and loosely connected with the arms G Gr, as shown inFig. 6, so that while capable of raising and lowering them it will notinterfere with their lateral movement to grasp and release the arms.

In the construction shown in Fig. 5 the lateral flanges h on the arms Gare omitted, and in lieu of the channeled support or guide H there areshown two guides Z and m at the front and rear of the arms.

Having thus described my invention, what I claim is- 1. In awick-raiser, two arms, comprising each a toothed portion cl, anoutwardly extending bar e, an upright part f, and thumb piece 9; incombination with a hinge pin connecting the upright parts f, and aspring urging the toothed portions toward each other.

2. In combination with the grooved or channeled guide H; the pivotedwick grasping arms provided with lateral flanges h.

3. In a lamp, the combination with the bowl provided with an opening andwith a guiding device adjacent thereto; of two vertically movablemembers hinged together by a vertical pivot pin and terminating at theirlower ends with arms to directly grasp the wick, and at their upper endswith thumb pieces or handles by pressing together which the graspingarms are separated; and a spring to hold the arms in engagement with thewick.

In witness whereof I hereunto set my hand in the presence of twowitnesses.

JOHN A. FREY.
